CellBench Data • scMerge

Introduction

This is a benchmarking single-cell data comprising of 3 different human lung adenocarcinoma cell lines. This experiment was designed induce different batch effects into the data.

Integration challenge

Prior to integration, there is a strong separation effect by multiple batch effects.
One of the batch effects is the different protocols with significant depth differences.
The experimental design poses extra difficulties as cell lines were cultured separatedly and the same batch was processed in 3 different ways.
